Benjamin Peterson46ea4f72009-06-27 21:40:27 +00007What's New in Python 3.2 Alpha 1?
8=================================
9
10*Release date: XX-XXX-XXX*
11
12Core and Builtins
13-----------------
14
Victor Stinner33109a12010-05-28 21:55:10 +000015- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
16 used anymore and it was never documented.
17
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000018- Issue #2844: Make int('42', n) consistently raise ValueError for
19 invalid integers n (including n = -909).
20
Mark Dickinsondc787d22010-05-23 13:33:13 +000021- Issue #8188: Introduce a new scheme for computing hashes of numbers
22 (instances of int, float, complex, decimal.Decimal and
23 fractions.Fraction) that makes it easy to maintain the invariant
24 that hash(x) == hash(y) whenever x and y have equal value.
25
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000026- Issue #8748: Fix two issues with comparisons between complex and integer
27 objects. (1) The comparison could incorrectly return True in some cases
28 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
29 (2) The comparison raised an OverflowError for large integers, leading
30 to unpredictable exceptions when combining integers and complex objects
31 in sets or dicts.
32
Victor Stinner7d79b8b2010-05-19 20:40:50 +000033- Issue #8766: Initialize _warnings module before importing the first module.
34 Fix a crash if an empty directory called "encodings" exists in sys.path.
35
Victor Stinner9ca9c252010-05-19 16:53:30 +000036- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
37 encoding and surrogateespace error handler instead of the locale encoding to
38 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
39
Victor Stinner372ac5e2010-05-17 01:26:01 +000040- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
41 (instead of strict) error handler to escape surrogates
42
Victor Stinnerae6265f2010-05-15 16:27:27 +000043- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
44 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000045 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
46 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +000047
Victor Stinner59e62db2010-05-15 13:14:32 +000048- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
49 error handler, not only the default error handler (strict)
50
Victor Stinnerb744ba12010-05-15 12:27:16 +000051- Issue #8610: Load file system codec at startup, and display a fatal error on
52 failure. Set the file system encoding to utf-8 (instead of None) if getting
53 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
54
Victor Stinner0964ee12010-04-30 16:48:45 +000055- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
56 PyUnicode_FromString() to support surrogates in the filename and use the
57 right encoding
58
Georg Brandl8569e582010-05-19 20:57:08 +000059- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
60
Victor Stinnerb9a20ad2010-04-30 16:37:52 +000061- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
62
Benjamin Petersonfb886362010-04-24 18:21:17 +000063- Issue #8419: Prevent the dict constructor from accepting non-string keyword
64 arguments.
65
Victor Stinner14284c22010-04-23 12:02:30 +000066- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
67 indirectly Python signal handlers anymore because mywrite() ignores
68 exceptions (KeyboardInterrupt)
69
Victor Stinner31be90b2010-04-22 19:38:16 +000070- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
71 unicode string (eg. backslashreplace)
72
Victor Stinnerdcb24032010-04-22 12:08:36 +000073- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
74 you have to convert your bytearray filenames to bytes
75
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +000076- Issue #7332: Remove the 16KB stack-based buffer in
77 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
78 benefit compared to the dynamic memory allocation fallback. Patch by
79 Charles-François Natali.
80
Benjamin Peterson8380dd52010-04-16 22:51:37 +000081- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
82 passed to bytes or bytearray.
83
Philip Jenvey0805ca32010-04-07 04:04:10 +000084- Issue #7301: Add environment variable $PYTHONWARNINGS.
85
Benjamin Petersond856ab62010-04-06 21:55:16 +000086- Issue #8329: Don't return the same lists from select.select when no fds are
87 changed.
88
Mark Dickinson3318d292010-04-06 16:53:17 +000089- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
90 on 64-bit machines. The shift count for either left or right shift is
91 permitted to be up to sys.maxsize.
92
Benjamin Peterson8daa49e2010-04-03 22:55:48 +000093- Ensure that tokenization of identifiers is not affected by locale.

100 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000101
Victor Stinner120c2122010-03-25 00:30:28 +0000102- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
103 is unknown
104
Victor Stinner808fc0a2010-03-22 12:50:40 +0000105- Issue #1583863: An str subclass can now override the __str__ method
106
Mark Dickinsond59b4162010-03-13 11:34:40 +0000107- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
108 PyMemberDefs could produce an internal error; raise TypeError instead.
109
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000110- Issue #7845: Rich comparison methods on the complex type now return
111 NotImplemented rather than raising a TypeError when comparing with an
112 incompatible type; this allows user-defined classes to implement their own
113 comparisons with complex.
114
Victor Stinner52f6dd72010-03-12 14:45:56 +0000115- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
116 (SIGINT). If an error occurs while importing the site module, the error is
117 printed and Python exits. Initialize the GIL before importing the site
118 module.
119
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000120- Issue #7173: Generator finalization could invalidate sys.exc_info().

129
Larry Hastings1373a072010-02-24 22:49:58 +0000130- Issue #5939: Add additional runtime checking to ensure a valid capsule
131 in Modules/_ctypes/callproc.c.

144 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
145 and PyOS_string_to_double instead. See issue #5835 for the original
146 deprecations.
147
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000148- Issue #7385: Fix a crash in `MemoryView_FromObject` when
149 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
150
Mark Dickinsonbc099642010-01-29 17:27:24 +0000151- Issue #7788: Fix an interpreter crash produced by deleting a list
152 slice with very large step value.
153
Eric Smithf7bb5782010-01-27 00:44:57 +0000154- Issue #7766: Change sys.getwindowsversion() return value to a named
155 tuple and add the additional members returned in an OSVERSIONINFOEX

157 suite_mask, and product_type.
158
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000159- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
160 could crash in many places because of the PyByteArray_AS_STRING() macro
161 returning NULL. The macro now returns a statically allocated empty
162 string instead.
163
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000164- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
165 where the right hand operand is a set of constants, by turning the set into
166 a frozenset and pre-building it as a constant. The comparison operation
167 is made against the constant instead of building a new set each time it is
168 executed (a similar optimization already existed which turned a list of
169 constants into a pre-built tuple). Patch and additional tests by Dave
170 Malcolm.
171
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000172- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
173 methods of bytes, bytearray and unicode objects by using a common
174 implementation based on stringlib's fast search. Patch by Florent Xicluna.
175
Mark Dickinson45b63652010-01-16 18:10:25 +0000176- Issue #7632: Fix various str -> float conversion bugs present in 2.7
177 alpha 2, including: (1) a serious 'wrong output' bug that could
178 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
179 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000180 strings corresponding to subnormal values, (3) a memory leak for
181 some values large enough to cause overflow, and (4) a number of
182 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000183
Benjamin Petersonaea44282010-01-04 01:10:28 +0000184- The __complex__ method is now looked up on the class of instances to make it
185 consistent with other special methods.

188 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
189
Benjamin Petersond12362a2009-12-30 19:44:54 +0000190- Issue #7604: Deleting an unset slotted attribute did not raise an
191 AttributeError.

Mark Dickinson9ab44b52009-12-30 16:22:49 +0000193- Issue #7534: Fix handling of IEEE specials (infinities, nans,
194 negative zero) in ** operator. The behaviour now conforms to that
195 described in C99 Annex F.
196
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000197- Issue #1811: improve accuracy and cross-platform consistency for
198 true division of integers: the result of a/b is now correctly
199 rounded for ints a and b (at least on IEEE 754 platforms), and in
200 particular does not depend on the internal representation of an int.
201
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000202- Issue #6834: replace the implementation for the 'python' and 'pythonw'
203 executables on OSX.
204
205 These executables now work properly with the arch(1) command:
206 ``arch -ppc python`` will start a universal binary version of python
207 in PPC mode (unlike previous releases).
208
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000209- Issue #7466: segmentation fault when the garbage collector is called

217
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000218- Issue #7085: Fix crash when importing some extensions in a thread
219 on MacOSX 10.6.
220
Philip Jenvey1309adb2009-11-17 03:43:14 +0000221- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.

224 implement the relevant rich comparison methods.
225
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000226- Issue #7298: fixes for range and reversed(range(...)). Iteration
227 over range(a, b, c) incorrectly gave an empty iterator when a, b and
228 c fit in C long but the length of the range did not. Also fix
229 several cases where reversed(range(a, b, c)) gave wrong results, and
230 fix a refleak for reversed(range(a, b, c)) with large arguments.
231
Raymond Hettingerfc438512009-11-01 20:55:33 +0000232- Issue #7244: itertools.izip_longest() no longer ignores exceptions

394 pymalloc allocator will be automatically disabled when running under
395 Valgrind. This gives improved memory leak detection when running
396 under Valgrind, while taking advantage of pymalloc at other times.

617
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000618- Issue #4814: timeout parameter is now applied also for connections resulting
619 from PORT/EPRT commands.
620
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000621- Issue #8463: added missing reference to bztar in shutil's documentation.
622
Ronald Oussoren84151202010-04-18 20:46:11 +0000623- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
624 (as long as the user didn't specify 'automatic proxy configuration').
625
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000626- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
627 code as stated in RFC-959 at chapter 5.4.
628
Victor Stinner738446f02010-04-18 00:00:44 +0000629- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
630 surrogates.
631
Antoine Pitrou0454af92010-04-17 23:51:58 +0000632- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000633 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

637
Victor Stinner0e59cc32010-04-16 23:49:32 +0000638- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
639 the current working directory.

651
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000652- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
653 module now takes an optional timeout argument in seconds. Timeout support
654 relies on the system threading library, so as to avoid a semi-busy wait
655 loop.
656
Victor Stinner485fb562010-04-13 11:07:24 +0000657- Issue #8383: pickle and pickletools use surrogatepass error handler when
658 encoding unicode as utf8 to support lone surrogates and stay compatible with
659 Python 2.x and 3.0
660
R. David Murrayb2416e52010-04-12 16:58:02 +0000661- Issue #7585: difflib context and unified diffs now place a tab between
662 filename and date, conforming to the 'standards' they were originally
663 designed to follow. This improves compatibility with patch tools.
664
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000665- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
666 character sets will now consistently use a Content-Transfer-Encoding of
667 7bit rather than sometimes being marked as 8bit.
668
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000669- Issue #8375: test_distutils now checks if the temporary directory are still
670 present before it cleans them.

676 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
677 and `ssl.OPENSSL_VERSION_NUMBER`.
678
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000679- Add functools.total_ordering() and functools.cmp_to_key().
680
Mark Dickinson089b00c2010-04-03 15:51:03 +0000681- Issue #8257: The Decimal construct now accepts a float instance
682 directly, converting that float to a Decimal of equal value:
683
684 >>> Decimal(1.1)
685 Decimal('1.100000000000000088817841970012523233890533447265625')
686
Mark Dickinson98127c32010-04-03 11:18:52 +0000687- Issue #8294: The Fraction constructor now accepts Decimal and float
688 instances directly.
689
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000690- Issue #7279: Comparisons involving a Decimal signaling NaN now
691 signal InvalidOperation instead of returning False. (Comparisons
692 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
693 are now hashable; Decimal signaling NaNs remain unhashable.
694
695- Issue #2531: Comparison operations between floats and Decimal
696 instances now return a result based on the numeric values of the
697 operands; previously they returned an arbitrary result based on
698 the relative ordering of id(float) and id(Decimal).
699
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000700- Added a subtract() method to collections.Counter().
701
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000702- Issue #8233: When run as a script, py_compile.py optionally takes a single
703 argument `-` which tells it to read files to compile from stdin. Each line
704 is read on demand and the named file is compiled immediately. (Original
705 patch by Piotr Ożarowski).
706
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000707- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
708 form feed (0x0C) are now considered linebreaks, as specified in Unicode
709 Standard Annex #14. See issue #7643.
710 http://www.unicode.org/reports/tr14/
711
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000712- Comparisons using one of <, <=, >, >= between a complex instance and
713 a Fractions instance now raise TypeError instead of returning
714 True/False. This makes Fraction <=> complex comparisons consistent with
715 int <=> complex, float <=> complex, and complex <=> complex comparisons.
716
Antoine Pitrou39b35432010-03-23 00:25:54 +0000717- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
718 some methods (such as oss_mixer_device.fileno()) were not available.
719 Initial patch by Bertrand Janin.
720
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000721- Issue #8205: Remove the "Modules" directory from sys.path when Python is
722 running from the build directory (POSIX only).
723
Antoine Pitrou910bd512010-03-22 20:11:09 +0000724- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
725 didn't support chflags() (for example ZFS under FreeBSD). The error is
726 now silenced.
727
R. David Murrayca2edce2010-03-22 17:48:48 +0000728- Issue #7860: platform.uname now reports the correct 'machine' type
729 when Python is running in WOW64 mode on 64 bit Windows.
730
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000731- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
732 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
733 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000734
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000735- Issue #4282: Fix the main function of the profile module for a non-ASCII
736 script, open the file in binary mode and not in text mode with the default
737 (utf8) encoding.
738
Florent Xicluna54467e02010-03-21 12:29:50 +0000739- Issue #8179: Fix macpath.realpath() on a non-existing path.

744
Benjamin Peterson689a5582010-03-18 22:29:52 +0000745- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
746 detected.
747
Martin v. Löwis4b003072010-03-16 13:19:21 +0000748- Issue #6716/2: Backslash-replace error output in compilall.
749
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000750- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
751 with Tcl/Tk-8.5.
752
Matthias Klosec33b9022010-03-16 00:36:26 +0000753- Issue #8140: extend compileall to compile single files. Add -i option.

756 the locale.
757
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000758- The internals of the subprocess module on POSIX systems have been replaced
759 by an extension module (_posixsubprocess) so that the fork()+exec() can be
760 done safely without the possibility of deadlock in multithreaded applications.
761
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000762- subprocess.Popen now has restore_signals and start_new_session features.
763 The default of restore_signals=True is a new behavior compared to earlier
764 Python versions. This means that signals such as SIGPIPE are not ignored
765 by default in subprocesses launched by Python (Issue #1652).
766
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000767- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
768 cElementTree module is updated too.

777 the replacement were all bytes. Patch by Antoine Pitrou.
778
Gerhard Häringf9cee222010-03-05 15:20:03 +0000779- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
780 bugs and allows loading SQLite extensions from shared libraries.

Victor Stinnercee3ae82010-03-04 00:29:24 +0000785- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
786 reset also the pointer to the current pointer context.
787

Florent Xiclunac279ebf2010-02-27 11:31:21 +0000796- Issue #691291: codecs.open() should not convert end of lines on reading and
797 writing.
798

813 to be ignored only to the first file. Noted by Bogdan Opanchuk.
814
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000815- Issue #7597: curses.use_env() can now be called before initscr().
816 Noted by Kan-Ru Chen.
817

824 bytecode file when it was less then 8 bytes.
825
Mark Dickinson84230a12010-02-18 14:49:50 +0000826- Issue #7633: In the decimal module, Context class methods (with the
827 exception of canonical and is_canonical) now accept instances of int
828 and long wherever a Decimal instance is accepted, and implicitly
829 convert that argument to Decimal. Previously only some arguments
830 were converted.
831
R. David Murray1f449142010-02-11 00:15:05 +0000832- Issue #7835: shelve should no longer produce mysterious warnings during
833 interpreter shutdown.
834
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000835- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
836 in XML processing instructions and comments. These raw characters are
837 allowed by the XML specification, and are necessary when outputting e.g.
838 PHP code in a processing instruction. Patch by Neil Muller.

850 type is specified. Patch by Brian Curtin.
851
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000852- Issue #6939: Fix file I/O objects in the `io` module to keep the original
853 file position when calling `truncate()`. It would previously change the
854 file position to the given argument, which goes against the tradition of
855 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
856
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000857- Issue #7610: Reworked implementation of the internal
858 :class:`zipfile.ZipExtFile` class used to represent files stored inside
859 an archive. The new implementation is significantly faster and can
860 be wrapped in a :class:`io.BufferedReader` object for more speedups.
861 It also solves an issue where interleaved calls to `read()` and
862 `readline()` give wrong results. Patch by Nir Aides.
863
Jesse Noller1f0b6582010-01-27 03:36:01 +0000864- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

866 the worker before that worker is terminated, and a new one created to
867 replace it.
868
Benjamin Petersond6326642010-01-27 02:25:58 +0000869- Issue #7792: Registering non-classes to ABCs raised an obscure error.

1026 to execute file paths that refer to source or compiled Python files as well
1027 as zipfiles, directories and other valid sys.path entries that contain a

Victor Stinnere125f132010-05-15 21:04:43 +00001048 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001049 recursive locks as fast as regular non-recursive locks (previously,

1070 reading from stdin so that existing input does not confuse it and

1212 abstract method required by ResourceLoader.

Florent Xiclunab14930c2010-03-13 15:26:44 +00001470- Issue #7849: Now the utility ``check_warnings`` verifies if the warnings are
1471 effectively raised.
1472
Florent Xiclunac9c79782010-03-08 12:24:53 +00001473- The four path modules (genericpath, macpath, ntpath, posixpath) share a
1474 common TestCase for some tests: test_genericpath.CommonTest.
1475
Florent Xicluna0e62a142010-03-06 17:34:48 +00001476- Print platform information when running the whole test suite, or using

1483 is run with the -OO flag. Tests requiring docstrings are skipped.
1484
Ezio Melotti184bdfb2010-02-18 09:37:05 +00001485- Issue #7712: test.support gained a new `temp_cwd` context manager which is
1486 now also used by regrtest to run all the tests in a temporary directory.
1487 The original CWD is saved in `support.SAVEDCWD`.
1488 Thanks to Florent Xicluna who helped with the patch.
1489
Mark Dickinsonedff7af2010-02-13 18:34:53 +00001490- Issue #7924: Fix an intermittent 'XXX undetected error' failure in
1491 test_capi (only seen so far on platforms where the curses module
1492 wasn't built), due to an uncleared exception.
1493
Florent Xicluna3f88c0e2010-03-19 14:40:31 +00001494- Issue #7728: test_timeout was changed to use support.bind_port instead of a
1495 hard coded port.
R. David Murraye9e95932010-02-06 05:00:15 +00001496
R. David Murray445448c2009-12-20 17:28:31 +00001497- Issue #7376: instead of running a self-test (which was failing) when called
1498 with no arguments, doctest.py now gives a usage message.
1499

1501
R. David Murray596da442009-12-14 23:06:11 +00001502- Issue #7498: test_multiprocessing now uses test.support.find_unused_port
R. David Murray83396232009-12-14 22:45:15 +00001503 instead of a hardcoded port number in test_rapid_restart.

Victor Stinnere125f132010-05-15 21:04:43 +00001505- Issue #7431: use TESTFN in test_linecache instead of trying to create a
R. David Murrayba311052009-12-04 00:09:14 +00001506 file in the Lib/test directory, which might be read-only for the
1507 user running the tests.
1508
R. David Murray35768ad2009-11-15 00:23:21 +00001509- Issue #7324: add a sanity check to regrtest argument parsing to
1510 catch the case of an option with no handler.
1511
R. David Murray7dc72cc2009-11-14 16:13:02 +00001512- Issue #7312: Add a -F flag to run the selected tests in a loop until
1513 a test fails. Can be combined with -j.
1514
Antoine Pitrou060cee22009-11-13 16:29:04 +00001515- Issue #6551: test_zipimport could import and then destroy some modules of
1516 the encodings package, which would make other tests fail further down
1517 the road because the internally cached encoders and decoders would point
1518 to empty global variables.
1519
Antoine Pitrou941ee882009-11-11 20:59:38 +00001520- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1526 tests instead of tempfile.tempdir. This prevents the tests from sharing state
1527 between concurrent executions on the same system.
1528
Brett Cannon0ae45112009-11-05 01:17:22 +00001529- Issue #7248: In importlib.test.source.util a try/finally block did not make
1530 sure that some referenced objects actually were created in the block before
1531 calling methods on the object.
1532
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001533- Issue #7222: Make thread "reaping" more reliable so that reference
1534 leak-chasing test runs give sensible results. The previous method of
1535 reaping threads could return successfully while some Thread objects were
1536 still referenced. This also introduces a new private function:
1537 :func:`_thread._count()`.
1538
R. David Murray27144602009-10-19 15:26:16 +00001539- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1540 longer runs the risk of causing the worker thread to fail.
1541
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001542- Issue #7055: test___all__ now greedily detects all modules which have an
1543 __all__ attribute, rather than using a hardcoded and incomplete list.
1544
R. David Murray0bc11ae2009-10-18 22:18:17 +00001545- Issue #7058: Added save/restore for things like sys.argv and cwd to
1546 runtest_inner in regrtest, with warnings if the called test modifies them,
1547 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001548
Mark Dickinson2e304402009-10-04 18:43:54 +00001549- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1550
Brett Cannon3c273842009-07-20 00:14:29 +00001551- Fixed tests in importlib.test.source.test_abc_loader that were masking
1552 the proper exceptions that should be raised for missing or improper code
1553 object bytecode.
1554
Brett Cannonb49c70c2009-07-15 04:08:33 +00001555- Removed importlib's custom test discovery code and switched to
1556 unittest.TestLoader.discover().

1562
Antoine Pitroua69ba652010-01-18 21:20:53 +00001563- iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were
1564 added to the `Tools/` directory. They were previously living in the
1565 sandbox.

1771
Antoine Pitroue4501852009-05-14 18:55:55 +00001772- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1773 library. This means, for example, that opening an UTF-16 text file in
1774 append mode doesn't add a BOM at the end of the file if the file isn't
1775 empty.
1776
R. David Murray74b89242009-05-13 17:33:03 +00001777- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1778 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1779 corrects a pydoc regression.
1780
R. David Murray99352742009-05-07 18:24:38 +00001781- Issue 5955: aifc's close method did not close the file it wrapped,
1782 now it does. This also means getfp method now returns the real fp.

1825Core and Builtins
1826-----------------
1827
Mark Dickinson865e01a2009-05-07 16:37:01 +00001828- Issue #5914: Add new C API function PyOS_string_to_double, and
1829 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1830
Eric Smith741191f2009-05-06 13:08:15 +00001831- Issue #3382: float.__format__, complex.__format__, and %-formatting
1832 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1833 affects nan -> NAN and inf -> INF.
1834
Mark Hammond5a607a32009-05-06 08:04:54 +00001835- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1836 in all operations, including splitdrive, split, etc. splitunc() now issues
1837 a PendingDeprecation warning.
1838
Eric Smith63376222009-05-05 14:04:18 +00001839- Issue #5920: For float.__format__, change the behavior with the
1840 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1841 to be like 'g' but with at least one decimal point and with a
1842 default precision of 12. Previously, the behavior the same but with
1843 a default precision of 6. This more closely matches str(), and
1844 reduces surprises when adding alignment flags to the empty
1845 presentation type. This also affects the new complex.__format__ in
1846 the same way.
1847
Martin v. Löwis011e8422009-05-05 04:43:17 +00001848- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1849
R. David Murrayb18500d2009-05-04 22:59:07 +00001850- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1851 shadowed by classtype's, even if it was None. property now
1852 inserts the __doc__ into the subclass instance __dict__.
1853
Antoine Pitrou244651a2009-05-04 18:56:13 +00001854- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1855 sequences. Patch by Nick Barnes and Victor Stinner.
1856
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001857- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001858
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001859- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1860 received a new method, detach(). detach() disconnects the underlying stream
1861 from the buffer or text IO and returns it.
1862
Mark Dickinson33841c32009-05-01 15:37:04 +00001863- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1864 floats with absolute value over 1e50. Also remove length
1865 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1866 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001867
Eric Smith741191f2009-05-06 13:08:15 +00001868- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001869 format(complex(1, 2./3), '.5') now produces a sensible result.
1870
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001871- Issue #5864: Fix empty format code formatting for floats so that it
1872 never gives more than the requested number of significant digits.
1873
Eric Smith6dc46f52009-04-27 20:39:49 +00001874- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1875 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1876
Eric Smithcc32a112009-04-26 21:35:14 +00001877- Issue #5835: Deprecate PyOS_ascii_formatd.
1878
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001879- Issue #4971: Fix titlecase for characters that are their own
1880 titlecase, but not their own uppercase.
1881
Benjamin Peterson193152c2009-04-25 01:08:45 +00001882- Issue #5283: Setting __class__ in __del__ caused a segfault.
1883
Mark Dickinsonad476da2009-04-23 19:14:16 +00001884- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1885 z involves nans, infs or negative zeros.
1886
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001887- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001888
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001889- Issue #1869 (and many duplicates): make round(x, n) correctly
1890 rounded for a float x, by using the decimal <-> binary conversions
1891 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1892 consistently agrees with format(x, '.2f').
1893
Benjamin Petersonae937c02009-04-18 20:54:08 +00001894- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1895 some builtin types.
1896
Eric Smith0923d1d2009-04-16 20:16:10 +00001897- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1898
Eric Smith35e84722009-04-16 20:21:28 +00001899- Issue #5515: str.format() type 'n' combined with commas and leading
1900 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001901
1902- Implement PEP 378, Format Specifier for Thousands Separator, for
1903 floats.
1904
Mark Dickinson3370cce2009-04-17 22:40:53 +00001905- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001906 1e11, not 1e12. This avoids printing 13 significant digits in
1907 situations where only 12 of them are correct. Example problem
1908 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1909 long time.)
1910
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001911- Issue #1580: On most platforms, use a 'short' float repr: for a
1912 finite float x, repr(x) now outputs a string based on the shortest
1913 sequence of decimal digits that rounds to x. Previous behaviour was
1914 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001915 Another minor difference is that the new repr switches to
1916 exponential notation at 1e16 instead of the previous 1e17; this
1917 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001918
1919 There's a new sys attribute sys.float_repr_style, which takes
1920 the value 'short' to indicate that we're using short float repr,
1921 and 'legacy' if the short float repr isn't available for one
1922 reason or another.
1923
1924 The float repr change involves incorporating David Gay's 'perfect
1925 rounding' code into the Python core (it's in Python/dtoa.c). As a
1926 secondary consequence, all string-to-float and float-to-string
1927 conversions (including all float formatting operations) will be
1928 correctly rounded on these platforms.
1929
1930 See issue 1580 discussions for details of platforms for which
1931 this change does not apply.
1932
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001933- Issue #5759: float() didn't call __float__ on str subclasses.
1934
Georg Brandlabc38772009-04-12 15:51:51 +00001935- The string.maketrans() function is deprecated; there is a new static method
1936 maketrans() on the bytes and bytearray classes. This removes confusion about
1937 the types string.maketrans() is supposed to work with, and mirrors the
1938 methods available on the str class.
1939
R. David Murraydc6da8a2009-04-09 22:16:43 +00001940- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1941 its clarity and its speed.
1942
Matthias Klose091c7b12009-04-07 13:24:27 +00001943- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1944 to avoid compiler warnings.
1945
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001946- Issue #3739: The unicode-internal encoder now reports the number of characters
1947 consumed like any other encoder (instead of the number of bytes).

2083
Benjamin Peterson7fe98532009-04-02 00:33:55 +00002084- Issue #5499: The 'c' code for argument parsing functions now only accepts a
2085 byte, and the 'C' code only accepts a unicode character.
2086
Georg Brandl406b3d82009-04-11 21:24:37 +00002087- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

2089
Brett Cannon0759dd62009-04-01 18:13:07 +00002090- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
2091
Georg Brandlab6f2f62009-03-31 04:16:10 +00002092- Fix a segfault when running test_exceptions with coverage, caused by
2093 insufficient checks in accessors of Exception.__context__.
2094
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002095- Issue #5604: non-ASCII characters in module name passed to
2096 imp.find_module() were converted to UTF-8 while the path is
2097 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00002099- Issue #5126: str.isprintable() returned False for space characters.
2100
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002101- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2102 the end sys.path, for compatibility with the system install of Python.
2103
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002104- Issue #4688: Add a heuristic so that tuples and dicts containing only
2105 untrackable objects are not tracked by the garbage collector. This can
2106 reduce the size of collections and therefore the garbage collection overhead
2107 on long-running programs, depending on their particular use of datatypes.
2108
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002109- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

2114 2**15 for the internal representation of integers, for performance
2115 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
2116 --enable-big-digits option to configure, which overrides the
2117 default. Add sys.int_info structseq to provide information about
2118 the internal format.

2121 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2122 and sizeof(Py_UNICODE) == 2.
2123
Eric Smith8ec90442009-03-14 12:29:34 +00002124- Issue #5237: Allow auto-numbered fields in str.format(). For

2126
Antoine Pitrou652e7072009-03-13 19:25:20 +00002127- Issue #5392: when a very low recursion limit was set, the interpreter would
2128 abort with a fatal error after the recursion limit was hit twice.
2129
Matthias Klose042f1332009-04-04 14:32:42 +00002130- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

2176
Lars Gustäbel42e00912009-03-22 20:34:29 +00002177- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2178 forever on incomplete input. That caused tarfile.open() to hang when used
2179 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2180 partial bzip2 compressed data.
2181
Mark Dickinson79f52032009-03-17 23:12:51 +00002182- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinson87ec0852009-02-09 17:15:59 +00002230- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2231 it now forces its argument to double before testing for infinity.
2232
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002233- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002242
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002243- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002244 were suppressing all exceptions. These include list() and bytearray().

2250 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2251 evaluation loop is compiled with a new dispatch mechanism which gives
2252 speedups of up to 20%, depending on the system, on various benchmarks.

2268 to str, bytes and bytearray could be optimized away by the compiler, letting
2269 the interpreter segfault instead of raising an error.
2270
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002271- Issue #3720: Fix a crash when an iterator modifies its class and removes its

2297 flag to work properly. Furthermore, when specifying -u, the text stdout
2298 and stderr streams have line-by-line buffering enabled (the default being
2299 to buffer arbitrary chunks of data).
2300
Raymond Hettinger35631532009-01-09 03:58:09 +00002301- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2302 instead of ints (reducing its size from 4 to 8 times thereby reducing
2303 Python's overall memory).
2304
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002305- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2306 an existing .py counterpart, override the co_filename attributes of all
2307 code objects if the original filename is obsolete (which can happen if the
2308 file has been renamed, moved, or if it is accessed through different paths).
2309 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2310
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002311- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2312 one byte. Also fixes the meaning of len() so that it returns the number of
2313 items, rather than the size in bytes.
2314
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002315- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2316
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002317- Issue #4747: When the terminal does not use utf-8, executing a script with

2325
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002326- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2327 where the tp_hash and tp_dict slots are both NULL.
2328
Georg Brandlccc47b62008-12-28 11:44:14 +00002329- Issue #4759: None is now allowed as the first argument of

2381 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2382 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2383 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou08838b62009-01-21 00:55:13 +00002703- Issue #5008: When a file is opened in append mode with the new IO library,
2704 do an explicit seek to the end of file (so that e.g. tell() returns the

2989 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2990 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2991 skip the tests if DISPLAY is defined but can't be used.
2992
R. David Murraya21e4ca2009-03-31 23:16:50 +00002993- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002994 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002995 from test support, which does the conversion.
